Abstract
The utility model provides an end surface special echelon sealing ring with a section in an echelon shape and a middle opened a taper hole, and the generatrix and the center line of the taper hole form an angle of Alpha<1> of 5 to 12 degrees, while the outer surface of the sealing ring has an angle Alpha<2> of 5 to 12 degrees between the generatrix and the center line. Being in particular used for the seal of quick pressing device connected without a bolt in the water pump test, except for a perfect sealing effect and being narrow and reliable, the utility model has the advantages of improving the performance accuracy of the water pump test, and moreover, promising no sealing ring dropping in assembling and disassembling, thereby improving the assembling and disassembling efficiency.
Description
Technical field
The utility model relates to water pump test device, is a kind of special-purpose trapezoidal seal ring of end face that is exclusively used on the water pump test device.
Background technique
Water pump is widely used in the every field as the universal machine product.Because water pump is important fluid machinery, so the water pump of various models after assembling is finished in manufacturing, all needs to carry out the test of various technical performances on test stand.Because when water pump test device adopts the fast compressing device of non-bolt connection at present, import and export Sealing and adopt existing standard piece, this standard piece sealing tightness is lower, causes bigger trouble for the installation water pump, and influence the experimental performance of water pump, and the working life of Sealing is lower.
Summary of the invention
The purpose of this utility model is, provides a kind of end face special-purpose trapezoidal seal ring, and it is exclusively used in the fast compressing device that the non-bolt of water pump test device connects, and makes that to import and export sealing tight, improves the accuracy of pump test performance, and makes easy installation and removal.
The utility model is achieved through the following technical solutions for achieving the above object: the special-purpose trapezoidal seal ring of a kind of end face, and the sectional shape of seal ring is trapezoidal, cone shape hole, the angle α of the bus of cone shape hole and center line are offered in the seal ring middle part
1Be 5 °-12 °, the angle α of seal ring outer surface bus and center line
2It is 5 °-12 °.The height H of described seal ring is the 4-8 millimeter.Described trapezoid cross section is an isosceles trapezoid.The angle α of the bus of described cone shape hole and center line
1Be 8 °, the angle α of seal ring outer surface bus and center line
2It is 8 °.The angle α of the bus of described cone shape hole and center line
1Be 6 °, the angle α of seal ring outer surface bus and center line
2It is 6 °.The angle α of the bus of described cone shape hole and center line
1Be 12 °, the angle α of seal ring outer surface bus and center line
2It is 12 °.
The utility model has the advantages that: be exclusively used in the sealing on the fast compressing device that adopts the non-bolt connection in the pump test, good sealing effect, tight reliable, improved the accuracy of pump test performance, and when dismounting, seal ring is difficult for dropping out, and can improve dismounting efficient.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
The contrast accompanying drawing elaborates to the utility model.
The sectional shape of seal ring described in the utility model is trapezoidal, cone shape hole 1 is offered at the middle part of seal ring, in order tightly to cooperate with seal groove when installing and using, and makes seal ring be difficult for dropping out when dismounting, prolong its working life, with the bus of cone shape hole 1 and the angle α of center line
1Be designed to 5 °-12 °, the outer surface bus of seal ring and the angle α of center line
2Design 5 °-12 °.Further scheme of the present utility model is: the angle α of the bus of cone shape hole 1 and center line
1Be 8 °, the angle α of seal ring outer surface bus and center line
2It is 8 °.Preferred scheme is: the angle α of the bus of cone shape hole 1 and center line
1Be 6 °, the outer surface bus of seal ring and the angle α of center line
2It is 6 °.The utility model can also have following scheme: the angle α of the bus of cone shape hole 1 and center line
1Be 5 °, 10 °, 12 ° etc., the outer surface bus of seal ring and the angle α of center line
2Be 5 °, 10 ° and 12 ° etc.This angle has guaranteed that further seal ring can better tightly cooperate with seal groove reliably, guarantees pump test result's accuracy.The utility model dismounting for convenience, prolong the working life of seal ring, the height H of seal ring is designed to the 4-8 millimeter, preferably: 5 millimeters, when installing and using, make the height of the trapezoidal sectional shape height of seal ring greater than seal groove, seal groove also is designed to trapezoidal, interior big outer little, during with assurance dismounting parts, seal ring is difficult for dropping out.
